What Is EXTREME-POE-MIB?
EXTREME-POE-MIB is an Extreme Networks proprietary MIB for managing Power over Ethernet (PoE) on Extreme enterprise switches, part of the wired LAN switching technology area. It exposes system-wide PoE configuration (admin enable, disconnect precedence, usage threshold, power-supply mode, legacy device support) and per-slot power-sourcing-equipment (PSE) data including power limits and consumed power for switches with modular PoE slots. It is explicitly useful for monitoring hardware status: power supply mode and per-slot power limit versus actual consumption reveal whether a switch chassis is nearing its PoE power budget, which threatens the ability to power additional PoE devices like phones, cameras, or access points. It is a vendor-specific extension typically deployed alongside the standard IETF POWER-ETHERNET-MIB (RFC 3621) for base per-port PoE status, and administrators performing an EXTREME-POE-MIB download from Extreme Networks' support site would compile it together with that standard MIB for complete PoE visibility. It is deployed on Extreme Networks modular/stackable switches in campus/enterprise networks powering PoE endpoints.
IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-POE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
What Can Be Monitored
- PoE system admin enable state
- per-slot PoE power limit
- per-slot PoE power consumption
- power supply mode/redundancy
- PoE usage threshold
- legacy PoE device support enable
Supported Devices
- Extreme Networks 5420 Series switch — universal switch with 802.3bt 30/60/90W PoE
- Extreme Networks 4000 Series — 90W PoE, multi-gigabit access switch
Monitoring Examples
An administrator would poll extremePethSlotConsumptionPower against extremePethSlotPowerLimit per extremePethPseSlotEntry (indexed by extremePethSlotNumber) to see how much of a slot's PoE power budget is in use, and check extremePethSystemUsageThreshold to know when a warning trap fires. If extremePethSystemPowerSupplyMode indicates a redundant/degraded power supply, or extremePethSlotConsumptionPower approaches extremePethSlotPowerLimit, PoE devices on that slot risk being denied power or disconnected per extremePethSystemDisconnectPrecedence.

The amount of power allocated to a PoE device is based upon the PoE device class and/or the port's extremePethPortViolationPrecedence setting. For example, in the default configuration of extremePethPortViolationPrecedence set to maxAdvertisedOperator(3), and the extremePethPortOperatorLimit set to 15400, a PoE device is allocated 15.4 watts. |

| I32 extremePethPortReservedBudget | 1.3.6.1.4.1.1916.1.27.2.1.1.2 | Integer32 | read-write | Controls individual port maximum power level. Value is 0 or in the range of 3000..30000 |
| INT extremePethPortViolationPrecedence | 1.3.6.1.4.1.1916.1.27.2.1.1.3 | INTEGER | read-write | Sets the violation precedence for the specified ports. A value of advertised-class will remove/deny power in the case an 802.3af compliant PD consumes power beyond its advertised class limit. A value of operator-limit will remove/deny power should the PD consume power beyond the configured operator-limit. A value of max-class-operator will remove/deny power if the PD consumes power beyond the maximum of the detected class limit and the operator-limit. A value of none will remove/deny power in case the PD device exceeds the maximum allowable wattage according to regulatory maximum of 20 W. Default is max-class-operator which allows operation of both 802.3af compliant and legacy PDs. |

| INT extremePethSystemDisconnectPrecedence | 1.3.6.1.4.1.1916.1.27.4.2 | INTEGER | read-write | Controls the disconnect function of power management. When the power drain exceeds the available power budget, due to a rise in power consumption after power is allocated to the ports, the PoE controller disconnects one of the ports to prevent overload on the power supply. There are two controls: Lowest-priority: next port connected causes a shutdown of the lowest priority port. Deny-port: next port is denied power, regardless of priority. |
| I32 extremePethSystemUsageThreshold | 1.3.6.1.4.1.1916.1.27.4.3 | Integer32 | read-write | The usage threshold expressed in percents for comparing the measured power and initiating an alarm if the threshold is exceeded. |
| INT extremePethSystemPowerSupplyMode | 1.3.6.1.4.1.1916.1.27.4.4 | INTEGER | read-write | Controls whether the power supply operate in redundant or load-sharing mode. Systems which do not provide redundant or load-sharing operations will return an error on setting, and notApplicable on read. |
| INT extremePethSystemLegacyEnable | 1.3.6.1.4.1.1916.1.27.4.5 | INTEGER | read-write | Controls whether legacy is supported by the system. This is only supported on S300-24 stackables currently. |
